VVKN

Swirl Ceiling Diffuser with Fixed Blades

Description

The VVKN swirl diffuser with xed blades is a

comfortable air distribution element. The diffuser face

is supplied with a radially alligned set of variously

shaped blades, which guarantee an even distribution

of swirl supply air into the occupied zone. The VVKN

swirl diffuser can be installed onto an air duct using a

plenum box with a horizontal or a vertical connection

by a exible circular tube or the SPIRO duct. VVKN can

be used for both supply or extract air. The swirl diffuser

with xed blades enables an intensive swirl based on

its swirl outlet. It can be used for ventilation, as well as

supplying cold or warm air.

The mounting consists of installing the plenum box to the ceiling using draw-bars and mounting the diffuser face onto the plenum box using a centric screw which is included in the delivery.
